IMPROVEMENT :N- wlNnow-saisie FASTENERS.

Specification forming part of Letters Patent No. 38,609, dated May 19,1863.

To all whom it may concern:

Be it known that` I, BENJAMIN D. SKID- MORE, of the city, county', andState of New York, have invented a new aux'.I Improved VVind'ow-SashFastening; and I do hereby declare' that the following is a full, clear,and exact description of the same, reference being Y had to theaccompanying drawings, making a partoiltliisspecification, inv which-Figur`1"is avrtical central section of my invrntio'n applied to"arwindow, taken in the line w flig. 2, the window being also bisected.Fig. 2 is a front viewof the same.

Similar letters of reference indicate corresponding parts in the twofigures.

v-Llhis invention relatesto a sash-fastei'iing of' that class whicharevplaced at thejc'euter of the upper crossrail of the lower sash, and.which are designed for keeping the sashes or locking the same in aclosed state only.

'The object of the invention is to obtain a fasteningf the classspecified, which may be unfastened by -an upward "pressure, the ysamewhich is employed to raiset-he lower sash, and thereby avoid theinconvenience of employing both hands' in raising the sash, or twomanipulations, as hitherto requiredbne touniock or release the sashes,and the other to raise the lower one. .Y

To enable those skilled in the art to fully understand and construct myinvention,I will proceed to describe it.

A represents the lower, and B the upper, sash of a window, constructedand arranged in the usual way', and (l is a case, of rectangular orother suitable form, which is secured to the center of the uppercrossrail, a, of the lower sash, A. Within this case G a slide bolt, D,is fitted over a suitable guide, b, and said bolt y is provided with apendent bar, c, between which and the front end of the case C a spiralspring, D', is placed, one end of the spring l being attached to the barc, and the other enda `to the front partof apendant, c', attached toguide Islas shown in Fig. l. This spring has` a tendency. to keep thefront end of the bolt D out from the case, and the under -side ofthefront part -of the bolt is rounded onbeveled, as shown at d, so thatit may catch into a nosing, e, at the center of the lower crossfrail, f,of the upper sash, B, when the lower sash, A, is vshoved down.l l

v E represents a bent lever, which is it'ted in the case C on a properfulcrum, b, back of the bolt D. The upper end `of this lever isconnected by a rod, g, with the back vend of the `bolt D, and to thelower end of the lever E there is attached.V by a pivot, h, a pendentrod, F, which passes through the center of the cross-rail a.' i

'Erom the above description it will be seen that by pressing upward therod F the bent lever E- will be actuated, its upper part thrownv back,and the bolt D drawn back and out from the nosing, so that by continuingthe upward pressure the lower sash may be raised. Assoon as the rod F isrelieved from the upward pressure of the hand the spring D will' throwout thebeveled end ofthe bolt D, and when the sash is lowered the boltD. will engage itself' with the nosing e, owing to the vbeveled end d ofthe bolt D. Thus it will be I claim as new, and desire to secure byLetters Patent, is-

The combination of the slide-bolt D, .spring D', lever E,"and pendentrod F, all arranged in connection with the case C and nosing e, tooperate las and for th'eopurposeset forth.
